In the presence of Pd(OAc)2, couples with aryldiazonium fluoroborates to give 3-aryl-4-sulfolenes which are readily isomerized with triethylamine to the 3-aryl-3-sulfolenes, providing a source of the corresponding 2-arylbutadienes: Synth. Commun., 26, 231 (1996).

Lithiation occurs at the 2-position; subsequent alkylation and thermal extrusion of SO2 gave a polyene intermediate in a synthesis of the taxane ring system: J. Org. Chem., 62, 2957 (1997).
